Title: Polyarylate resin
Inventor: CHOE KIL-YONG
IPC: C08F290/00
Filed: 1991-10-16
Granted: 1995-06-21
Abstract: The polyarylate resin has formula (I), where n is not less than 1. A process for producing formula (I) comprises polycondensing terephthaloyl and isophthaloyl chloride with bisphenol A, and end-capping the pre-polymer obtained with 4-nadimidobenzoyl chloride. The cured resin is produced by hardening formula (I) for 3-5 hrs. at 290˜300 deg.C under 250 psi.
